US secondary-sanctions wind-down expires Sept 23, 2026, choking Iranian carriers’ international operations
On 23 September 2026 a US Treasury wind-down authorization expired at 12:01 a.m. EDT, removing OFAC aviation authorizations and creating near‑total prohibitions on transactions with 27 designated Iranian carriers — a move that risks grounding their international services and expands secondary‑sanctions exposure for third‑country banks and service providers.
The desk brief
On 23 September 2026 a US Treasury wind-down authorization expired at 12:01 a.m. EDT, removing OFAC aviation authorizations and creating near‑total prohibitions on transactions with 27 designated Iranian carriers — a move that risks grounding their international services and expands secondary‑sanctions exposure for third‑country banks and service providers.
The removal of aviation wind‑down authorizations (effective 23 Sept 2026) forces foreign fuel suppliers, ground handlers, insurers and banks to choose between servicing designated Iranian carriers or risking US secondary sanctions and loss of dollar access. That raises correspondent‑banking and trade‑finance compliance costs and could hit Egyptian correspondent corridors (Banque Misr UAE was flagged for processing Iran‑linked flows), with knock‑on effects for African banks with Gulf trade links and insurers pricing aviation risks.
Monitor whether major Gulf, Turkish or African airports and fuel/handling firms cease services to designated Iranian carriers within days of Sept 23, and any formal US licensing guidance or enforcement actions.
